A:AnswerThe ram is soldered onto the motherboard itself so it isn’t upgradable without professional methods sadly, so you’ll have to buy the ram that comes with the laptop (which I believe can go up to 16 gb from what I’ve seen so far)
The internal storage can be upgraded, however this laptop uses an M.2 NVMe slot (I believe there’s only one SSD slot which would be taken up already with the storage you buy that comes with the laptop so you’d have to swap and transfer the data from your old SSD to the new one)
A:AnswerThis laptop has a 512GB solid state storage (SSD) drive instead of a HDD (Hard Disk Drive). Both drive types store your data, but how they store and retrieve the data is part of the difference between the two styles of drives.
A:AnswerI'll edit this if I demo/purchase the laptop and have a more definitive answer, but in the meantime: The Q420 - which you can find on their website by Googling "Zenbook 14X OLED Q420" - has several references to "Intel Evo"; it's even in the model number: Q420VA-EVO.I7512.
Intel Evo - which you can find by searching "Overview of Intel Evo" - is a certification that Intel provides to laptops to make it easier to find the commonly desired "premium" features. One of these is Biometric logins through Windows Hello (fingerprint, facial, OR bluetooth proximity).
Unfortunately, it's hard to tell where it is to confirm through pictures. The later lines of laptops now offer it on the power button or under the trackpad without the little square they used to have. The 14X website talks about the IR facial recognition, the 14 website talks about it's fingerprint scanner. But given Intel Evo, some confirmation it does, and then the 14 having one - it stands to reason the 14X probably has one too.
